Abstract
In this research, we used and analyzed the data obtained from Ministry of Education General Directorate of Assessment and Examination Services. Analyzed data consists of ABİDE 2016 Turkish-A booklet, and the data was collected from 6000 participants. We aimed to find out whether the subgroups to which the ABİDE reading test items are applied contain DIF among the gender subgroups. We chose logistic regression analyzes because of their suitability to parametric data sets. Ordinal logistic regression analysis was determined as the main analysis method because the responses given to the items contain an ordinal structure. As a result of the DMF analysis, we did not determine any differential item functioning. The results obtained indicate that ABIDE substances do not have medium and high degree differential item function for subgroups. The findings can be interpreted as the relevant items are valid for analyzed subgroups. However, conducting exploratory analyzes that may lead to the formation of existing findings in future research will contribute to the establishment of a national monitoring-evaluation system. Finally, the fact that the ABIDE project follows an open data policy such as PISA and shares broad data, will increase the reliability of the project and allow more in-depth data to be obtained.
